ValueError: too many values to unpack in Django models

Question

Test.py

The files serves to test everything within the memepost app.

from django.test import TestCase
from memepost.models import memepost, memepostForm
from datetime import date 
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

class memepostTestCase(TestCase):
    def setUp(self):
        memepost.objects.create(title="foo", 
            model_pic="/site_media/media/pic_folder/casual_headshot.jpg", 
            date=date(2017, 05, 14))
        memepost.objects.create(title="bar", 
            date=date(2017,05, 1))
            
    def test_memepost_enters_database(self):
        foo = memepost.objects.get("foo")
        bar = memepost.objects.get("bar")
        self.assertEqual(foo.date, "6/15/17")
        logger.debug("foo date is equal to %s", foo.date)
        self.assertEqual(bar.model_pic, "no-img.jpg")
        logger.debug("bar is equal to %s", bar.model_pic)

models.py

This file serves to be scheme for creating memes in my database.

from __future__ import unicode_literals
from django.forms import ModelForm
from django.db import models

# Create your models here.
class memepost(models.Model):
    title = models.CharField(max_length=140)
    model_pic = models.ImageField(upload_to='pic_folder/', default='pic_folder/no-img.jpg')
    date = models.DateTimeField()

    def __unicode__(self):
        return self.title

class memepostForm(ModelForm):
    class Meta:
        model = memepost
        fields = ["title", "model_pic", "date"]

error

Okay, so I am getting this warning, but I think the problem has something to do with the title paramater since I call a get function by the title. I hope I was clear.

You are not providing keyword argument for get manager method

def test_memepost_enters_database(self):
    foo = memepost.objects.get(title="foo")
    bar = memepost.objects.get(title="bar")
    ...
